The Hawaii Intermediate Court of Appeals affirmed a family court decision that awarded primary physical custody of two children to M.F. over C.T. The ruling, issued on August 31, 2026, is significant for parents involved in custody disputes, highlighting the court's discretion in determining the best interests of children.

The case, known as M.F. v. C.T. (CAAP-25-0000180), began when C.T. appealed a family court ruling from August 26, 2025. The family court had previously held a trial on February 10 and 11, 2025, where it decided to award joint legal custody to both parents but granted primary physical custody to M.F. This decision was based on various factors, including the children's welfare and stability.

In the appeal, C.T., who represented himself, raised several points of contention regarding the family court's findings. He argued that the court made errors in its assessment of educational stability, medical management, and the conduct of the custody investigation. C.T. claimed that the family court's decision was flawed and sought to overturn the ruling.

The court ruled that C.T.'s appeal lacked sufficient evidence to support his claims. The appellate judges, including Presiding Judge Keith K. Hiraoka and Associate Judges Kimberly T. Guidry and Daniel M. Gluck, noted that C.T. failed to provide necessary transcripts from the trial, which made it difficult to review his arguments. The court stated, "the burden is upon appellant in an appeal to show error by reference to matters in the record, and [appellant] has the responsibility of providing an adequate transcript."

The court also emphasized that it would not disturb the family court's decisions unless there was a clear abuse of discretion. They found no such abuse in this case. The family court had determined that M.F. provided a stable environment for the children, and C.T. did not present enough evidence to challenge this finding. The court concluded that C.T. had not demonstrated any error by the family court.

One of C.T.'s main arguments was that the family court erred in concluding that M.F. provided educational stability for the children. C.T. claimed that the children had significant absenteeism while in M.F.'s care. However, the appellate court found that C.T. did not provide adequate support for his assertion and disregarded it. The ruling stated that "C.T. provides no support for this assertion, and we therefore disregard it." The court also addressed C.T.'s claims about the management of the children's medical care and the alleged bias in the custody investigation. In both instances, the court found that C.T. had not identified any errors made by the family court. The court noted that the family court's findings were based on credible evidence, including a report from the Child Custody Investigation Unit (CIU).

The ruling has implications for future custody cases in Hawaii. It reinforces the principle that family courts have wide discretion in making custody decisions based on the best interests of children. The court's decision also emphasizes the importance of providing adequate evidence when appealing a family court ruling.

Moving forward, this ruling may influence how parents approach custody disputes, particularly regarding the need for thorough documentation and evidence during family court proceedings. The decision underscores the importance of presenting a strong case in custody matters, as failure to do so can result in unfavorable outcomes.

Details were not available in the court filing regarding whether C.T. plans to appeal this ruling further. However, the appellate court's decision stands as a significant precedent in child custody law in Hawaii, affirming the family court's authority to make decisions that prioritize the welfare of children.
